STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not Applicable.

BACKGROUND OF THE INVENTION

The present application relates generally to telephone systems andspecifically to telephone systems that provide for real-time textcaptioning for the hard of hearing.

Modern telecommunication services provide features to assist those whoare deaf or hard of hearing. One such feature is the text telephone(TTY) also known as a telecommunication device for the deaf (TDD). TTYsallow for text communication through the telephone system by generatingtones that may be transmitted by analog telephone lines in response to auser typing letters on a keyboard.

Hearing users may communicate with deaf users who have TTY devicesthrough so-called “relays.” A relay is a service funded by telephonecommunication surcharges that provides a “call assistant” whointermediates between a deaf user and a hearing user. The call assistantcommunicates with the deaf user using a TTY and communicates with thehearing user by voice over a standard telephone line.

A relay service may also be used to help those who are not deaf, buthard of hearing, by providing a captioned telephone. With a captionedtelephone, a user who is hard of hearing may carry on a normal telephoneconversation with a hearing user while a text transcription of the wordsspoken by the hearing user is displayed on the telephone. The texttranscription allows the hard of hearing user to confirm his or herunderstanding of the spoken words. Unlike with a conventional relayservice, captioned telephone requires extremely fast text transcriptionusing a computer executed voice recognition system (typically withrevoicing by a trained operator) so that the text captioning is asnearly as possible contemporaneous with the spoken words.

Text captioned telephones of this type are marketed under the servicemark CAPTEL and described in U.S. Pat. Nos. 6,307,921 and 6,075,842assigned to the assignee of the present invention and herebyincorporated by reference.

A text captioned telephone system employs a relay service in a modewhere the relay transmits both the voice of the hearing user and a textstream of the spoken words by that user. A telephone or display deviceof the receiving hard of hearing user provides a text display fordisplaying the captions.

In a single-line text captioned telephone, text and voice signals may bereceived over a single telephone line and separated electronically. Thetext captioned telephone includes software that automatically dials therelay, and providing the relay with the telephone number of the ultimatedestination of the call. For incoming telephone calls, the hard ofhearing user must normally hang up and redial the caller through therelay.

In a two-line text captioned telephone, a first telephone linecommunicates with the caller, and a second telephone line communicatesexclusively with the relay. The two-line system allows text captioningto be easily used on incoming calls by allowing the text captionedtelephone to dial out to the relay when the call is received and forwardthe necessary voice signal.

Many users of text-captioned telephony have jobs requiring significantuse of the telephone as made possible by text-captioning. These usersface a significant problem when they need to make use of telephonesystems outside of their normal work environment where text captioningtelephones may not be available or equipment such as cellular telephonesthat does not support text captioning must be used. Many workplaces useproprietary private branch exchange (PBX) telephone lines that do notsupport analog text captioning telephones, the latter which requirestandard telephone connections.

Other problems with existing telephony systems include an inability toconfirm that a communication has been initiated by a person at a callback telephone number, system users that allow others to use theiraccounts to share or avoid costs, lack of options for terminating callsto persons that use relay systems, inability for a relay user toidentify that an incoming call is a relay call and the identity of thecaller and how to present information to an emergency call center thatcan be used by the call center to call back or establish communicationwith a relay user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, in a first embodiment of the invention, a textcaptioned telephone system 10 may be implemented within a typical officehaving a PBX telephone terminal 12 and a desk top computer 14. The desktop computer 14 includes a display screen 16, a base unit 18 (includinga processor, memory, disk drives and importantly a sound card) and akeyboard or other entry device 20.

As is understood in the art, the PBX telephone terminal 12 may beconnected through an office wall jack 22 (not labeled in FIG. 1) to aPBX network 24 using a proprietary communication protocol. The PBXnetwork 24 communicates with a public switched telephone network 26 thatallows the PBX telephone terminal 12 to connect to an external telephoneterminal 28 to originate a call to the external telephone terminal 28 orto receive a call from the external telephone terminal 28.

The computer 14 may connect through an Ethernet card to an Ethernetnetwork 30, passing to a local router 32 to connect to the Internet 34or may use one of a number of well known wireless standards to connectto the local router 32.

Referring now also to FIG. 2, a voice signal tap 36 has a short cablestub 38 terminating in an RJ-12 jack 40 that may be received in thehandset jack for the main body of the PBX telephone terminal 12. The tap36 also provides a receiving socket for the RJ-12 jack 42 associatedwith the handset cord 44 so that the tap 36 may be simply interposedbetween the handset 46 and the main body of the PBX telephone terminal12 to conduct voice signals as analog audio signals there through.

A tap line 48 extending from the tap 36 terminates in a subminiaturephone jack 50 that may be received by audio input of the sound card ofthe base unit 18. The tap line conducts a portion of the voice signalsfrom the handset 46 to the sound card of the base unit 18.

The voice signals received by the computer 14 may be processed by aninternal program of a type well known in the art to encode the voicesignals as VOIP signals 52 that may be sent over the Internet to aserver 54 associated with a relay service 56. Programs for transmittingVOIP signal are commercially available from Skype of Luxembourg andVonage of New Jersey, USA. At the relay service 56, the encoded voicesignals may be converted back to an audio signal for transcription by acall assistant who produces corresponding captioning text 57 that may berelayed through conventional Internet transfer protocols back to thecomputer 14 where the text may be displayed.

In an alternative embodiment, a headset microphone and earpiece (notshown) may communicate separately with left and right sound cardchannels. This, along with echo canceling software in the computer 14allows the relay service 56 to separate the voice of the caption userfrom the other party for improved transcription and anonymity.

The relay service 56 may provide for human operators working with speechrecognition engines to rapidly translate voice signals into textstreams. The operation of such a relay is described in more detail inU.S. Pat. No. 6,567,503, assigned to the same assignee as the presentinvention and hereby incorporated by reference.

By placing the tap 36 in the path of the handset 46, analog audiosignals may be obtained, greatly simplifying the acquisition of theaudio signal without the need to contend with the PBX standard or theneed or awkward or unfamiliar computer associated microphones.

Referring now to FIG. 3, an office user wishing to avail themselves oftext captioning may start a text-captioning program 58 on the computer14 to provide a caller interface window 60 on the display screen 16. Thecaller interface window 60 may provide simple mouse or keyboard operatedcontrols including a caption button 62 that may be actuated by thecaller to begin the program's operation.

Referring to FIG. 4, upon pressing of the caption button 62, asindicated by process block 64, the computer 14 may initiate an Internetconnection to the relay service 56 by invoking a stored URL of the relayserver 54. At this time, the computer 14 may provide some information tothe relay including a serial number of the caller to validate thecaller's location for the purpose of identifying the particular publicauthority responsible for the relay call. The caller can be required toregister the program with a relay service database and the serial numbercan be used to authorize their use of the service, thus limitingfraudulent use of the relay service and allowing for local 911 serviceby providing information about the geographic location of the user.

As indicated by process block 66, the program 58 may then forward thetapped voice signals as VOIP signals to the relay server 54, and receivetext as indicated by process block 68 which may be displayed in text box70 of the caller interface window 60. The text box 70 includesconventional scroll-type controls 73 allowing text to be reviewed afterit has been received. The program 58 may also provide for normal fileoperations 75 including saving of text files, e-mailing text files, andthe like.

Upon completion of the call, the caller may press the caption button 62again to disconnect the call as indicated by process block 71. Thecaption button 62 may include an animation visually indicating its stateas being depressed or released or may change its label from “caption” to“end caption” indicating its changing function.

Importantly, this system allows for convenient and intuitive voicecommunication between a PBX telephone terminal 12 and telephone terminal28, either for making outgoing calls or ingoing calls, while allowingeither type of call to be captioned on demand without interruption ofthe telephone call or the need for specialized telephone equipment. Thissystem will also work without a PBX exchange and can work for a varietyof different telephone types not intended for text captioning.

Referring now to FIG. 5, in a second embodiment, a standard desk topcomputer 14 may work in conjunction with a standard telephone (i.e., nottext captioned), in this case a cell telephone 72, the latter of whichcommunicates through a cellular service 74 with the public switchedtelephone network 26, without a direct connection between the celltelephone 72 and the computer 14.

In this embodiment, the caller using the cell telephone 72 first callsthe relay service 56 as indicated by process block 76 of FIG. 6. Therelay service 56, per standard practice, receives telephone calls overthe public switched telephone network 26. The relay service 56 mayprovide an automated answering system that requests a telephone numberfrom the caller of the ultimate destination of the telephone call, inthis case, telephone terminal 28. As indicated by process block 78 ofFIG. 6, the caller may enter the requested telephone number by using thecaller's keypad on the cell telephone 72.

In the case where the relay service remains anonymous, in the sense thatthe call assistant does not speak directly with the caller, theanswering system may provide the caller with a personal identificationnumber (PIN) as indicated in process block 80. The relay service 56links the caller's particular incoming line to the PIN in an internaldatabase 57.

The caller, using a conventional browser on the desk top computer 14,then enters the URL of the server 54 of the relay service 56, asindicated by process block 82 of FIG. 6. This may also be done beforeinitiating the call to the relay service 56.

As shown in FIG. 7, the relay server 54 provides the caller with webpage86 offering a text box 88 allowing entry of the PIN received at processblock 80. The caller, by entering that PIN and press a captioninginitiation button 90, causes the relay service 56 to complete the callby connecting the incoming audio from the cell telephone 72 to thetelephone terminal 28. The relay service 56 then forwards captioningtext 55 over the Internet 34 to the caller through a text box 92 asindicated by process block 94. The text box 92 may use, for example, abrowser plug-in or instant messaging program to provide for a consistentupdating of the text as it is received, but otherwise requires nospecialized software on computer 14.

Alternatively and preferably, the caller may first contact the webpage86 using the computer 14 to provide the relay server 54 with both thenumber the caller wishes to dial and also the caller's own telephonenumber. The relay server 54 then calls the caller over the cell phone72. Once a connection is established with captions, the relay server 54dials to the other party. This automatically links the IP address to thetelephone connections without the need for PIN. The phone number of thecaller may be entered on the webpage 86 in a text box (not illustrated)and the destination phone number may be entered in another text box (notillustrated) similar to those described for the PIN.

The use of a web page and browser plug in to avoid the need forspecialized software to be on the desktop computer 14 is also applicableto the earlier embodiment of FIG. 1.

At the end of the call as indicated by process block 96, the caller maypress the captioning initiation button 90 again to terminate the call.The captioning initiation button 90 may reflect this new purpose, ofterminating the captioning, by changing its label.

Again, in this embodiment, no specialized text captioning equipment isrequired, but the system makes use of commonly available office andtelephone equipment to provide for text captioning that is not limitedto a particular location, but which may be used in any location whereInternet and telephone access may be had. In this regard, computer 14may, for example, be any Internet appliance, for example, a wirelessmobile laptop or the like. Thus a caller may work from a hot spot usinga cell telephone and a wireless laptop to obtain competent textcaptioning.

In a variation on this embodiment, set-up of the call (e.g. providingthe relay service 56 with the destination phone number) may beaccomplished using the desktop computer 14 rather than via telephone 72.When the caller calls the relay service 56, the caller enters a pinnumber to connect the call to the captioning or the connection may bemade by linking the callers phone number with a number previouslyentered on the computer 14.

In this embodiment, identification of the particular governmental entityresponsible for reimbursement for the captioning can be obtained fromthe information of the public switched telephone network 26 per standardpractice.

In a variation on this embodiment, new 3G cellular services allow theuse of both cellular voice and data connections simultaneously using acellular phone. In this case, the browser on a desktop computer 14 maybe replaced with a browser on the cell phone which provides a telephoneand Internet appliance, all in one.

Referring now to FIG. 8 in a third embodiment, a single advancedInternet appliance may be used to replace the need for a telephone. ThatInternet appliance, for example, may be a standard computer 14 equippedwith a microphone and headphone assembly 100 for making VOIP calls or aVOIP telephone 102 providing for display capabilities on screen 104.Many PBX systems now allow for the connection of VOIP phones.

Referring also to FIGS. 9 and 10, in a first variation on thisembodiment, a program 108 executed by the computer 14 provides a callerinterface window 110 on the display screen 16 of the computer allowingthe initiation of a VOIP connection as indicated by process block 112 ofFIG. 10. The caller interface window 110 provides a standard virtualtelephone keypad 114 by which a telephone number of a telephone terminal28 on the public switched telephone network 26 may be entered anddisplayed in text box 116. Pressing of a call button 120 initiates aVOIP telephone call. The basic process of initiating a VOIP call is wellunderstood in the art.

In the present invention, however, at any time, a captioning initiationbutton 122 may be pressed, causing initiation of a second VOIP telephonecall directly to the relay service 56 through the relay server 54 asindicated by process block 124. At this time, the VOIP signals 52exchanged between the computer 14 and telephone terminal 28 (optionallyvia the public switched telephone network 26) may be multicast to theserver 54 to be interpreted as voice signals by the relay service 56.The server 54 may also receive a serial number 125 identifying thecaller and assisting in allocation of relay service fees amonggovernmental entities. The relay service 56 returns captioning text 56transcribing the VOIP signals 52 back to the computer 14 to be displayedin text box 92 as indicated by process block 126.

The caller interface window 110 may also provide a volume meter 130aiding the caller in speaking to obtain sufficient signal strength fortransmission to telephone 28.

Alternatively, the call may be initiated as a captioned call by pressingthe captioning initiation button 122, then dialing the telephone number,in which case, setup information (e.g., the destination telephonenumber) together with a serial number, are forwarded to the relayservice 56 which may then initiate the VOIP call to the telephoneterminal 28 patching through signals received from computer 14 to thetelephone terminal 28.

As indicated by process block 132, the call may be terminated bypressing the call button 120 and/or captioning may be terminated bypressing the captioning initiation button 122.

When the computer 14 is used, a connection to the public switchedtelephone network 26 may also be provided for interception of emergencycalls, for example, to 911, routing those through the publicly-switchedtelephone network rather than through the Internet so as to provide forthe benefits of rapid identification of geographic location of thecaller inherent in calls made through the publicly-switched telephonenetwork and not always provided currently with the VOIP services.

Referring again to FIG. 8, the identical steps may be accomplished by aspecially programmed VOIP telephone 102, which requires only amodification in software to implement the same functions as thosedescribed above. The captioning initiation button in this case can beimplemented in software keystroke combinations without the need foradditional switches with the standard screen 104 on the VOIP telephoneserving as the text display and optional volume meter.

General purpose Internet appliances such as computer 14 make it possibleto expand the previous embodiments to the addition of a video camera 140providing video signals 142 to the Internet as well as the VOIP signals52 and the receipt of captioning text 55. Referring to FIG. 12, theaddition of video signals allows a video inset box 144 to be added tothe caller interface window 136, allowing viewing of the other party tothe conversation or the relay operator also having an Internet appliancesuch as a computer 14. This embodiment allows face-to-faceconversations, but also may allow, for example, the use of American SignLanguage or lip reading between users together with the captioningprovided by the text box 92. In other respects, the caller interfacewindow 136 may be identical to caller interface window 110 describedabove.

In a variation on this embodiment, a standard videophone may be used asmay be connected over a broadband Internet connection (or corporate LAN)to provide video and voice. Videophones are popular with both hearingpeople and deaf people that use sign language and provide a built incamera and display screen for the picture of the other party.

In this embodiment, the videophone user or video conference system usercan connect with the captioning service website and the service can sendthe captions not as IP text but as an IP video signal formatted to becompatible with the videophone. The captions are transmitted instead ofthe image of the caller, as video images of letters using standardcaptioning software that converts text to a video signals or as overlaidon the image of one caller using a video merging technique. In the casewhere a videophone provides a separate text display, this canalternatively be used for the captioning, as described above with theInternet phone, with the text being transmitted as IP text, that is,character data such as ASCII. Alternatively, IP text may be converted atthe videophone into image data to be displayed on a video screen as acaption. When IP text is received, the videophone may elect how the textis to be displayed, either as captions on a video image or as text withno other image. The IP text may be uniquely marked to identify it to thevideophone.

Additional Features

In addition to the various embodiments and aspects described above,additional features and aspects of the relay assisted systems describedabove are contemplated. A first additional feature is referred togenerally herein as a call confirmation process. To this end, asdescribed above, in at least some embodiments, when placing a relayassisted call, a hearing impaired user first opens her browser and linksto the relay server, logs into a service provider web page (see 86 inFIG. 7) and provides the relay server 54 (see FIG. 5) with both thenumber the caller wishes to dial and also the callers own telephonenumber. The relay server then calls the hearing impaired user giving theuser a prompt on her browser screen to answer the user's phone. When theuser answers the arriving call, the relay server automatically placesthe call to the second party (i.e., to the caller that the user wishesto dial). The relay 54 then conferences the two telephone connectionstogether and the call begins. At this point the relay servicetranscribes words spoken by the second party and the text captions aresent to the hearing impaired user's browser screen.

In this type system, there is a concern that someone could abuse thesystem in the following way. An unscrupulous third party could log intoa web page provided by a relay server 54, enter a call back telephonenumber that is not associated with the third party (i.e., a numberassociated with some other unsuspecting party), enter the second phonenumber that does not belong to the third party and cause the relay toconnect two unsuspecting parties. In this case, the relay server 54would dial the first telephone number and when an unsuspecting personanswers that call, the server 54 would make the call to the secondtelephone number and hence to the second unsuspecting party. When thesecond telephone is answered, at least one and potentially both of thepeople connected by the call would believe that the other person calledthem when in fact neither party placed the call.

The inventive call confirmation process has been developed to preventunscrupulous third parties from linking unsuspecting other parties usinga relay server 54 as described above. To this end, in general, theinventive call confirmation process proceeds as follows. After a hearingimpaired user contacts a web page to commence a call activity andprovides the callers own telephone number, the relay server 54 dials thecallers own telephone number and, generally simultaneously therewith,displays a message on the user's browser screen instructing the user toanswer the user's telephone and, thereafter, to perform someconfirmation activity to indicate that the user in fact intended tocommence the associated communication. For example, exemplaryconfirmation activities may include pressing one or a specific series ofdual-tone multi-frequency (DTMF) buttons on their telephone. As anotherexample, the confirmation activity may require the user to speak a wordor a specific phrase into the user's telephone receiver. Here, the relayserver 54 would be programmed so that it would not dial a second partyunless the instructed confirmation activity is performed using thetelephone associated with the call back telephone number. Thus, forexample, if the party answering the first telephone (i.e., the telephoneassociated with the call back telephone number) does not have thecaptioning screen in front of her, she will not know what confirmationactivity is required to continue the call and the relay server canterminate the call to eliminate the possibility of connecting twounsuspecting parties.

Referring now to FIG. 13, an exemplary call confirmation process 158 isshown in flow chart form. Referring also to the exemplary system shownin FIG. 5, at block 160, a first party (e.g., a hearing impaired systemuser) uses a network appliance 14 to link via network 34 to a relay 54server. Here, the network appliance may be any type of computer capableof running a browser or the like for providing web pages including apersonal computer, a laptop computer, a palm type computing device, atelephone, etc. Hereinafter, although many types of network appliancesare contemplated, the term computer will be used generally to simplifythis explanation unless indicated otherwise.

Referring still to FIGS. 5 and 13, at block 162, the first party usesthe computer to specify a first party call back telephone number as wellas a second party target telephone number (e.g., the telephone numberassociated with a second party that the first party wishes to dial). Atblock 164, relay server 54 dials the first party call back number. Inthe example of FIG. 5, the first party call back number corresponds totelephone 72. At block 168, relay 54 monitors first telephone activityto determine when the telephone 72 is answered. Once the first partytelephone 72 is answered control passes to block 170.

In at least some embodiments, at block 170, when telephone 72 isanswered, relay 54 presents information via telephone 72 indicating thatthe current call is an assisted call. This assisted call warning isprovided to help an unsuspecting person that did not intend to commencethe communication to recognize that the communication was in error andshould be terminated. For example, the assisted call warning mayindicate “This is an assisted call. If you did not commence this callactivity please hang up your telephone now.”

Next, at block 172, relay 54 presents confirmation activity instructionsvia a web page presented on the first party's computer 14 indicatingconfirmation activity that must be performed via the first party'stelephone 72 to continue the call process. Referring also to FIG. 14, anexemplary web page 150 for presenting confirmation activity instructionsis shown. Web page 150 includes instructions 154 and a code field 156.Exemplary instructions 154 instruct the user to “Please answer yourtelephone and enter the following 4-digit code via you telephone keypadto continue this call:”. A randomly generated 4-digit code is presentedin field 156 which is to be entered, in this example, to continue thecall.

Referring yet again to FIGS. 5 and 13, at block 174, after the firstparty's telephone 72 is answered, in at least some embodiments, relay 54may start a timer. Here, the relay timer is intended to time-out aperiod during which it is expected that the first party would be able tocomplete the confirmation activity required to continue the call. Forinstance, the time-out period may, in some cases, be 30 seconds. Here,where an unsuspecting user is confused by the call activity and does notterminate a call, it is contemplated that the relay 54 would terminatethe call automatically at the end of the time-out period.

At block 176, relay 54 monitors activities performed by the firstparty's telephone 72 to identify when the confirmation activity hasoccurred. In the present example, consistent with FIG. 14, the relay 54would monitor to determine when the 4-digit code in field 156 has beenentered via the first party's telephone 72. Where the confirmationactivity has not occurred, control passes to block 180 where relay 54determines whether or not the relay timer period is equal to thetime-out period. Where the relay timer period does not equal thetime-out period, control passes back up to block 176 where monitoringcontinue for the confirmation activity. Once the timer period equals thetime-out period at block 180, control passes to block 182 where relay 54terminates the call.

Referring once again to block 176, where the confirmation activityoccurs, control passes to block 178 where relay 54 calls a second partytarget telephone number and the call continues at block 179.

In at least some embodiments it is contemplated that all relay users maybe assigned a unique pass code or PIN number. Where a user has a PINnumber, referring again to FIG. 13, at block 172 the relay 54 mayprovide instructions for the user to simply enter the user's PIN numbervia the telephone keypad and, subsequently entry of the PIN number wouldbe used as confirmation activity at block 176.

In still other embodiments the confirmation activity instructions may bepresented via the first party's telephone 72 (i.e., the call backtelephone) and may require the first party to perform some confirmationactivity using the first party's computer 14. For example, theconfirmation activity instructions delivered via telephone 72 mayinstruct the user to “Enter the following 4-digit code via your browserto continue this call, 4397.” In this case, relay 54 would provide acode entry field via computer 14 and would monitor the code enteredtherein for confirmation activity. In this case, where an unsuspectinguser receives a call via telephone 72, the user would recognize that thecommunication is in error and would not participate by entering theconfirmation code via the computer 14. Here, after the time-out periodthe communication would be automatically terminated. Note that where auser cannot hear (e.g., in most cases a captioned telephone user ishearing impaired), a voice prompt on the telephone may not be usable tocause the user to enter something on their browser screen and thisembodiment would not work well.

In yet other embodiments, the confirmation activity may require entry ofa second party's target telephone number to continue a communication. Tothis end, referring again to FIG. 13, at block 162 the first party maysimply enter the first party's call back telephone number and may not berequired to enter the second party's target telephone number. Then, atblock 172, relay 54 may simply require that the first party enter thesecond party's target telephone number. Here, presumably, if the firstparty called back on telephone 72 is an unsuspecting party, whenrequested to enter a target telephone number to be called, the firstparty will recognize that the communication is in error and wouldterminate the call. However, where the first party answering telephone72 initiated the communication, the first party would be ready to enterthe second party's target telephone number. In this case, referringstill to FIG. 13, at block 176, instead of monitoring for confirmationactivity, relay 54 would simply monitor for an entered second partytarget telephone number. Where the second party's telephone number isentered, control passes to block 178 and then to block 179 to continuethe telephone call.

In still other embodiments, confirmation activity instructions may beprovided via a first party telephone that require activity using thefirst party's telephone where the instructions are provided along withan assisted call warning. Here, when a first party answers telephone 72(see again FIG. 5) the assisted call warning should be sufficient forthe first party to recognize whether or not the communication is inerror and, where the communication is in error, the first party couldterminate the call and not complete the confirmation activity. Where thefirst party initiated the communication, the first party could completethe confirmation activity via the first party telephone and continue thecommunication.

Thus, it should be appreciated that many different confirmationactivities are contemplated and ways of facilitating completion ofconfirmation activities are contemplated where a system user receivesconfirmation instructions via at least one of the user's computer ortelephone and is required to carry out confirmation activities via atleast one of the user's computer or telephone where at least one of thedevices used to give the confirmation activity instructions and thedevice used to perform the confirmation activity is controlled by thecall back party.

One additional feature aspect of a browser type relay assisted callsystem is referred to as flexible caller ID. In this regard, fortraditional telephone relay service (TRS) services, a relay userconnects to a relay service provider. The service provider then dials toa called party on another line. To provide functional equivalence of aregular telephone call, the relay service equipment forwards theidentity information of the in-bound caller on to the out-boundconnection. The result is that when the dialed party looks at a callerID display on their telephone, the dialed party sees that they arereceiving a call from the in-bound caller, not the relay service. Thisis referred to as “True Caller ID”. Here, the network caller ID systemis not designed to show more than a single identity. Therefore, thecaller ID service is limited to showing that a call is from an in-boundcaller or showing that the call is from a relay service but not both.

The browser type relay assisted call system described above is differentthan a traditional relay system. To this end, as described above, in abrowser type relay assisted call system, a system user receives noticeon their computer/browser screen (see again 14 in FIG. 5) that they arereceiving a call. The relay server 54 dials the user on a call backtelephone line for the voice part of a call. While a user's telephonecaller ID is limited to showing a single identity, the inventive systemactually has two displays including the caller ID display and thebrowser screen. As a result, it has been recognized that additionalinformation can be provided to a system user when the user receives acall that can help the user respond to the call in an appropriatefashion.

In one advantageous embodiment, at web page or browser screen can beprovided by relay server 54 that shows the identity of a caller when anincoming call is received. Here, the caller identity would be, in atleast some embodiments, the same information that would be displayed ona local caller ID box if that identity were presented via the user'stelephone. Since the browser screen is connected to the relay server 54,it is implied that the call is via the relay service and is an assistedcall type. In addition, the relay server 54 may be programmed to notforward the identity of the caller on to the caller ID display of thecaption user's telephone but instead to show the call is coming from therelay service provider. Here, by viewing the caller ID display of thetelephone and recognizing that a call is coming through the relayservice provider, the user can make a better informed decision as to howto respond to the incoming call. Thus, the user can see on her telephonecaller ID display that the call is coming through the relay serviceprovider which lets her know that she should look at or open the user'sbrowser to get captions for the call. Once the browser is open, the usercan see who is calling the user.

Should a user receive a call on the user's telephone where the caller IDdisplay does not show that the call is through the relay serviceprovider, she could elect not to answer the call if she does not haveaccess to the browser and she believes that she will need the captionfunction. In this case, she may opt to allow the call to go to voicemail so that a message can be obtained. Thereafter, when she has betteraccess to the browser, she may call back the caller via the relayservice provider.

Here, while the flexible caller ID concept is described generally incontext of a browser, the caller identification feature may beimplemented using an instant messenger client or some other customapplication.

Referring now to FIG. 15, an exemplary method 230 that is consistentwith the flexible caller ID concept is illustrated. Referring also toFIG. 5, at block 232, relay server 54 monitors relay links for secondparty calls to the first party. At block 234, where communication isattempted, control passes to block 236 where the relay 54 obtains thesecond party identification information. At block 238, relay 54 presentsrelay service provider identifying information via the first party'stelephone caller ID display. In addition, simultaneously, relay 54presents second party identifying information via the first partycomputer/browser/IM/custom application, etc. After block 238, the callactivity continues.

Referring to FIG. 16, an exemplary browser web page 210 is illustratedthat includes a caption 212 and second party identifying informationprovided in a field 214. The caption 212 indicates that “A CapTel callis arriving on your telephone from:” where the second party making thecall is identified in field 214. Referring to FIG. 17, an exemplary cellphone 216 is illustrated including a caller ID display 218 where therelay service provider identifying information is provided on display218. Thus, here, the first party receiving the call can identify thatthe call is via the relay service provider by viewing display 218 andcan also identify the second party caller via field 214.

In at least some embodiments it is contemplated that the flexible callerID feature may be provided via a handheld computer that includestelephone service so that the relay service provider identifyinginformation and the calling party information can be provided via asingle display screen. To this end, referring to FIG. 18, an exemplarycomputer/telephone device 220 is illustrated that includes a largedisplay screen 222. Here, the screen 222 may be used to present browserweb pages. In addition, a separate caller ID window 224 may be opened onthe screen 222 to present caller ID information when an incoming call isreceived by device 220. As shown in FIG. 18, when a call comes intodevice 220 and the device is linked to the relay server 54 forcommunication therewith, the calling party identifying information canbe provided via the browser screen as shown at 226 and a separate callerID window 224 can be opened up to identify the relay service provideridentifying information.

Yet one other aspect or feature that may be implemented via the systemsdescribed above is referred to as a call back feature. The call backfeature is particularly useful in the case of emergency calls that arefacilitated via the systems described above.

Making telephone relay service (TRS) 911 calls over an IP network hasbeen a problem for emergency service providers. The problem is that auser is connected to the emergency service provider via IP where the IPdoes not contain or imply any information about the caller's location.In addition, it is common for a 911 service provider to call back 911callers to resolve any issues that develop while servicing a call. Ifthe caller is using IP, the service provider cannot dial back to thecaller because the caller does not have a dialable call back number.Complicating matters further, calls through a relay come from a relaycenter and not from the caller's home. Thus, an emergency serviceprovider would have to know how to dial a relay center and to ask arelay employee to connect the service provider to the IP caller in orderto complete a call back communication.

The call back feature works as follows. When a first party connects to arelay server 54 as described above and dials 911 or some other emergencynumber, the relay server 54 assigns a temporary relay telephone numberto the first party. Here, the period of assignment is selected so as tobe generally sufficient to ensure that emergency service issues areresolved (e.g., 24-28 hours). In addition, the relay server 54 storesthe temporary telephone number along with any other information that canbe used to establish communication with the caller such as, forinstance, an IP address, the caller's telephone number, etc., in acorrelated fashion.

When the relay server 54 contacts the emergency service provider toservice a caller, the relay server 54 provides the temporary telephonenumber corresponding to the caller to the service provider call taker sothat the call taker can, if necessary, use the temporary number tosubsequently communicate with the caller. After the initial call isterminated, if the emergency call taker wants to call back the originalcaller for some reason, the call taker can simply dial the temporarytelephone number that was provided. The temporary telephone numberautomatically routes to the relay server 54 and is automaticallyconverted into information required to re-establish communication withthe original caller. Thus, in at least some embodiments, the convertedinformation includes an IP address and/or a dial back telephone numberfor the original caller and the call is completed to the user.

Referring now to FIG. 19, an exemplary method 252 that is consistentwith at least some embodiments of the call back feature described aboveis illustrated. Referring also to FIG. 5, at block 250, a first partyuses the first party's computer 14 to connect to the relay server 54. Atblock 254, the first party uses computer 14 to specify a targettelephone number to be called. At block 256, relay 54 recognizes thetarget telephone number as an emergency telephone number (e.g., 911). Atblock 258, server 54 assigns a temporary relay telephone number to thefirst party and at block 260 server 54 stores the temporary telephonenumber along with information that can be used to subsequently contactthe first party caller if desired. At block 260 the exemplaryinformation includes the caller's IP address as well as a first partycall back telephone number. At block 262, relay server 54 uses theemergency telephone number to establish a first communication with theemergency service provider and presents the temporary telephone numberto the emergency service provider (e.g., see phone 28 in FIG. 5).Thereafter, the first party and the service provider are linked via therelay 54 and the first communication commences.

In at least some embodiments a relay service may provide both thetemporary telephone number but also the actual telephone number (if theyhave one) of the caller. The actual number may be of value for emergencycall records. The PSAP would then know both the originating number andalso how to call back to a user with communications support of acaptioning relay. In addition, the relay may be able to identify atemporary call back number as an emergency call and to provide a higherpriority for the call, thus providing a more rapid response for thecall.

Referring still to FIGS. 5 and 19, at block 268 server 54 monitors thefirst communication to determine when the first communication wasterminated. Once the first communication is terminated, server 54 startsa timer to time-out a period during which the temporary telephone numberis assigned to the first caller. Here, for instance, an exemplarytime-out period may include 24 hours, 48 hours, one week, etc. At block272, server 54 determines whether or not the timer period is equal tothe time-out period and, once the timer period is equal to the time-outperiod, control passes to block 274 where server 54 unassigns thetemporary telephone number from the first party and the process ends.

At block 272, when the timer period has been shorter than the time-outperiod, control passes to block 278 where relay 54 monitors callsthereto to identify any calls routed to the relay using the firstparty's temporary telephone number. When relay 54 receives a call madeusing the first party's temporary telephone number, control passes toblock 280 where the relay server 54 uses the temporary telephone numberto identify the IP address and call back number for the first party. Atblock 282, relay server 54 establishes communication with the firstparty via the first party's computer and the call back telephone numberand a second communication between the service provider and th originalcaller continues.

In at least some embodiments it is contemplated that, instead ofassigning a temporary relay telephone number only when a targettelephone number is recognized as an emergency number, temporarytelephone number may be assigned to all calls through a relay server.Here, referring again to FIG. 19, process block 256 would be removed.Where temporary numbers are assigned to all relay calls, all emergencycalls would have temporary numbers and the process as described in FIG.19 would be similar.

After a temporary number is unassigned from a party, that temporarynumber can be reused by the relay server with a second party in the samemanner described above.

One additional aspect or feature that may be implemented using thesystem described above is referred to as a call terminating feature. Inthis regard, a relay user can also receive a relay assisted call from asecond party. To this end, a second party can call a relay user bydialing a toll-free relay service number and entering an area code andnumber of a person that they wish to contact via the relay service. Therelay server user the “call to number” as an index into a database andfinds an IP address for the relay user. The relay then sends a messageto the relay user's browser screen (see again 14 in FIG. 5) to alert theuser that a call is arriving and dials the user's call back number(i.e., the user's telephone 72). Here, the call continues the same wayas if the relay user had placed the call to the second party.

In the above case, if a second party attempts to call a relay user andthat user is not currently on-line or is not logged into the relayservice for some reason, a problem exists in that there is currently noway to terminate the call. Here the call terminating feature is providedto allow relay users to select preferential call terminating functions.

To this end, exemplary call terminating features may include, when therelay user is not on-line or is not logged into the relay service,playing an announcement for the calling party informing the callingparty that the party they are attempting to call is not available andthat the call should be tried again at a later time. Another option maybe for the relay server 54 to go ahead and dial the relay user's callback number and allow the user to either log in to the relay service viathe user's browser and answer the call or let the user's telephonevoicemail take a message. One additional option may be to have the relayserver 54 provide a captioned voicemail function by playing a message tothe caller asking the caller to leave a message, recording the voice ofthe caller, transcribing the message into text and, when the relay usernext logs into the relay service, inform the user of the waitingvoicemail. Here, when the relay user wants to retrieve voicemails, therelay server 54 would play the voice and text back to the user. Thislater method can operate as an accessible form of voicemail for hearingimpaired relay users. In at least some embodiments the relay user canselect how they prefer to handle calls when they are not logged into theservice and their preferences are kept as part of a user's profile whichcan be changed whenever the user wishes.

Referring now to FIG. 20, an exemplary method 290 for setting up orselecting one or a plurality of call terminating features isillustrated. At block 291 a set up process is started wherein a relayuser is provided a browser web page via the user's computer 14 thatincludes a plurality of possible terminating activities that may beperformed when a communication is attempted with the user and the useris not connected to the relay. Here, for instance, the possibleterminating activities may include providing a message indicating that acall cannot be completed, placing a call to the first party's telephoneor facilitating a voice to text transcription enabling the caller toleave a message for the relay user. At block 294 the relay user selectsone of the terminating activities via the browser page and at block 296the terminating activity that was selected by the user is stored in adatabase of user preferences for subsequent use. At block 298 the set upprocess ends.

Referring to FIG. 21, a method 300 for facilitating the call terminatingfeature is illustrated. At block 203, normal relay operation commencesand at block 304, the relay server 54 monitors communications at therelay. At block 306, when a communication is attempted with the firstparty's computer, control passes to block 308. At block 308, relayserver 54 determines whether or not the first party's computer is linkedto the relay. Where the first party's computer is linked to the relay,control passes to block 309 where the call process continues in a mannerdescribed above. However, at block 308, where the first party's computeris not linked to the relay, control passes to the terminating functionthat was selected by the user at block 294 in FIG. 20. Here, threepossible terminating selections are illustrated. A voice message to texttranscription process corresponds to blocks 310, 312, 314 and 316. Tothis end, at block 310, a voicemail message is provided to the callerinstructing the user to leave a voice message. At block 312, where avoice message is left, control passes to block 314 where the voicemessage is transcribed into a text message. At block 316, the textmessage is presented to the first party the next time the first party'scomputer is linked to the relay.

Referring still to FIG. 21, terminating feature 318 simply provides amessage that indicates that a call cannot be completed and that thecaller should try to call back at a later time. Terminating feature 320dials the relay user's telephone even when the relay user's computer isnot linked to the relay server 54 and allows a normal voicemail to beleft or can be used to provide a prompt to the relay user to log intothe service to complete an assisted call.

One additional aspect or feature that may be implemented using thesystems described above is referred to as a Lock Call Back Feature. Asdescribed above, in at least some embodiments a relay user can easilyspecify any call back number to be used to facilitate a relay assistedcall. The ability of a user to specify a call back number isparticularly useful because it allows a user to use virtually anycomputer browser and telephone to place a relay assisted call.

While the ability to specify a call back number is advantageous forvarious reasons, there is some concern that relay users may provideothers with their log in information and share their service privileges.The Lock Call Back Feature enables a relay service provider to lock acall back telephone number so that it cannot be changed easily by arelay user. When implemented, this feature essentially limits a relayuser so that the user can only use a single telephone and a singletelephone number associated therewith. Here the user cannot providetheir log in information to another party unless that other party isusing the same telephone as the user.
